The pipeline is widely applied in production and life. Among them, a pipe for transporting a liquid is liable to leak due to corrosion of the liquid after a long time use, or is liable to leak at a joint position of the pipe due to insufficient installation or the like. When the pipeline leaks, if the pipeline is not timely salvaged, the production life is seriously damaged. For example, a liquid cooling plate for radiating heat of hardware equipment in a data center is provided with a pipeline, so that cooling liquid flows in the pipeline to radiate heat and cool a heating component. The number of hardware devices in the data center is large, and if the pipeline leaks, the safety of various hardware devices in the data center can be greatly threatened.

Referring to fig. 1 to 5, a first aspect of the present utility model provides a pipe protector for mounting on a pipe 8. The pipe protector includes: a diversion layer 1, a water absorption layer 2, an outer shell 3 and a leakage sensor 7. The diversion layer 1 is covered on the outer wall of the pipeline 8 and is used for adsorbing liquid leaked by the pipeline 8; the water absorption layer 2 is covered on one side of the diversion layer 1 far away from the pipeline 8 and is used for absorbing liquid flowing out through the diversion layer 1; the outer shell 3 is connected with the outer wall of the pipeline 8 in a sealing way, and a sealing cavity for accommodating the water absorption layer 2 and the diversion layer 1 is formed between the outer shell and the outer wall of the pipeline 8; the leak sensor 7 is used to detect the presence of leaking liquid in the sealed cavity.

In the utility model, the liquid in the pipeline 8 is firstly adsorbed on the diversion layer 1 when leaked, and flows to the water absorption layer 2 and is adsorbed by the water absorption layer 2 when more liquid flows out, and the outer shell 3 plays a role in blocking the liquid from flowing out of the outer shell 3, so that the safety of the production and living environment is ensured. And the outer shell 3 is arranged on the outermost layer, so that the protection effect can be achieved, and the pipeline protection device is prevented from being scratched and pierced by external objects, and the tightness of the pipeline protection device is prevented from being influenced. In particular, the outer casing 3 and the pipe 8 may be screwed or flanged, but may be connected in other ways. In some examples, the outer casing 3 may include a first outer casing and a second outer casing, where the first outer casing and the second outer casing are respectively sleeved on two opposite outer walls of the pipeline 8, and the first outer casing and the second outer casing are fixed by threaded connection or flange connection, so that a sealed cavity is formed between the first outer casing and the second outer casing and the outer wall of the pipeline 8, and the first outer casing and the second outer casing can be fixed with the pipeline 8 in a sealing manner by threaded connection or the like. In addition, the junction of first shell body and second shell body still can be equipped with sealed rubber ring, promotes the leakproofness.

In the utility model, the leakage sensor 7 is used for detecting whether liquid exists in the sealed cavity, if so, the leakage sensor sends out leakage alarm information to the monitoring system, and maintenance personnel arrive at the site for rush repair after receiving the alarm information. And the structure of the pipeline protecting device can gradually permeate the stratum layer of the liquid, so that the outflow of the liquid is delayed, and more sufficient reaction time is reserved for the maintainer who receives the alarm to go to maintenance. In addition, the pipeline protection device is simple in integral structure and low in cost, is convenient for maintenance personnel to install and detach, and can be replaced quickly.

Referring to fig. 1, in some examples, the leak sensor 7 may be disposed in the sealed cavity, and then the leak sensor 7 is a contact leak sensor 7, when the pipe 8 leaks, the liquid enters the sealed cavity and contacts the leak sensor 7, and then the leak sensor 7 sends an alarm message after detecting the leakage of the liquid. Specifically, when the leakage sensor 7 is disposed in the sealed cavity, the outer casing 3 needs to be provided with a through hole for connecting the leakage sensor 7 with an external circuit board. Since the cable connected to the leakage sensor 7 passes through the through hole, a gap may be formed between the cable and the through hole, and sealing may be performed by using a sealant or the like in order to prevent leakage of liquid from the gap. It should be noted that, after the through hole is sealed, a sealed cavity can still be formed between the outer casing 3 and the outer wall of the pipeline 8, so that a better sealing effect is achieved.

In other examples, the leak sensor 7 may also be provided outside the outer housing 3, and the leak sensor 7 may be a non-contact leak sensor 7. The non-contact type leakage sensor 7 detects liquid by using infrared rays, ultrasonic waves and the like, but at the same time, the non-contact type leakage sensor 7 has certain requirements on the thickness and transparency of the outer shell 3, and specifically, the proper leakage sensor 7 can be selected according to actual requirements, or the outer shell 3 can be manufactured into the outer shell 3 with certain transparency according to the type of the selected leakage sensor 7.

Referring to fig. 2, as an embodiment, the pipe protection device may further include an inner housing 5, where the inner housing 5 is disposed between the diversion layer 1 and the water absorption layer 2, and the inner housing 5 is connected to an outer wall of the pipe 8 in a sealing manner, and forms a storage cavity 4 with the outer wall of the pipe 8, and the storage cavity 4 is used for storing the liquid flowing out through the diversion layer 1. The liquid flowing out of the pipeline 8 is firstly adsorbed on the diversion layer 1, and when the liquid is too much to enable the diversion layer 1 to further adsorb the liquid, the liquid flows out through the diversion layer 1. Because the storage cavity 4 is formed between the inner shell 5 and the outer wall of the pipeline 8, the liquid can be collected in the storage cavity 4 after flowing out through the guide layer 1, and the liquid can not continuously flow out to the outside under the blocking of the inner shell 5.

As an embodiment, the pipeline protection device further comprises a waterproof layer 6, the waterproof layer 6 is arranged between the water absorbing layer 2 and the outer shell 3 in a covering mode, and the waterproof layer 6 is used for blocking liquid absorbed by the water absorbing layer 2 from leaking. Thereby, the waterproof layer 6 can prevent the liquid of the water-absorbing layer 2 from continuing to flow out. In some examples, the waterproof layer 6 may be directly coated on the water-absorbing layer 2, and the waterproof layer 6 may also have elasticity. Therefore, after the water absorbing layer 2 absorbs the liquid and expands, the waterproof layer 6 can deform along with the liquid, namely, the waterproof layer 6 can always wrap the waterproof layer 6, and the waterproof effect is more remarkable.

As an example, the waterproof layer 6 is a Polyethylene (PE) film. Therefore, the polyethylene film has outstanding waterproof performance, elasticity and better flexibility, and can fully wrap the water absorbing layer 2.

As an example, the outer casing 3 has elasticity, and the water absorbing layer 2 absorbs the liquid and then presses the inner wall of the outer casing 3 to expand the outer casing 3 to the outside by the elastic force. Therefore, when the waterproof layer 6 is not arranged in the pipeline protection device, the waterproof layer 6 can be directly replaced by the outer shell 3, and materials are saved. In this way, the outer casing 3 not only plays a role in waterproofing, but also has elasticity, and the outer casing 3 can also elastically deform when the water absorbing layer 2 absorbs liquid and expands.

Referring to fig. 2, as an example, the leakage sensor 7 may include a first leakage sensor 71 provided between the outer wall of the pipe 8 and the fluid guiding layer 1, and the first leakage sensor 71 is used to detect whether there is leaked fluid between the outer wall of the pipe 8 and the fluid guiding layer 1. Thus, the first leakage sensor 71 is used for detecting leakage of the pipe 8 immediately after the leakage of the liquid, and when the first leakage is detected, alarm information is sent, so that maintenance personnel can receive the alarm information immediately after the leakage of the liquid, the leakage alarm information is more timely, and more sufficient reaction time is reserved for the maintenance personnel.

Referring to fig. 3, as an embodiment, the leakage sensor 7 may include a second leakage sensor 72 provided between the flow guiding layer 1 and the inner housing 5, and the second leakage sensor 72 is used to detect whether there is leaked liquid between the flow guiding layer 1 and the inner housing 5. Specifically, when the second leakage sensor 72 gives an alarm message, the liquid has already flowed through the diversion layer 1 to the diversion layer 1 and the inner casing 5, whereby the maintenance person can grasp the degree of leakage of the liquid of the pipe 8 when the leaked liquid is detected by the second leakage sensor 72 and gives an alarm message.

Referring to fig. 4, as an example, the leakage sensor 7 may include a third leakage sensor 73, the third leakage sensor 73 being provided between the inner case 5 and the outer case 3, the third leakage sensor 73 being for detecting whether there is leaked liquid between the inner case 5 and the outer case 3. Thus, when the third liquid leakage sensor 7 detects the leaked liquid, the serviceman can determine that the liquid has flowed between the inner case 5 and the outer case 3 after receiving the alarm information.

Referring to fig. 5, the pipe guard may include, as an embodiment, a first leakage sensor 71, a second leakage sensor 72, and a third leakage sensor 73. Through the layered arrangement of the first leakage sensor 71, the second leakage sensor 72 and the third leakage sensor 73, the alarm information sent by the leakage sensor 7 can reflect the leakage of the leaked liquid, so that a maintainer can judge the severity of the leakage of the pipeline 8, and a reference is provided for the repair work progress of the maintainer.

In some examples, the leak sensor 7 may further comprise a fourth leak sensor (not shown in the figures) which may be provided outside the outer housing 3, when the fourth leak sensor detects liquid then the liquid has flowed out of the outside of the pipe guard, suggesting that the leaking liquid has seriously compromised the safety of the external equipment.

As an example, the baffle layer 1 may be a nonwoven fabric. The non-woven fabric can absorb water or permeate water, and can be primarily adsorbed on the non-woven fabric after liquid flows out from the pipeline 8, and can guide the liquid to be reserved in the storage cavity 4 or the water absorption layer 2 after the non-woven fabric cannot further absorb the liquid.

As an example, the water absorbing layer 2 is made of a super absorbent resin material. Specifically, the super absorbent resin material can absorb several hundred times to thousands times the liquid of its own weight, and has strong water retention. Therefore, the water absorbing layer 2 has better water absorbing performance and water retaining performance, can absorb more leaked liquid, and reduces the risk of the liquid continuing to outflow. The water absorbing layer 2 may be made of other materials having water absorbing property and water retaining property according to actual needs.

A second aspect of the utility model provides a pipe system comprising a pipe 8 and a pipe protector as described above, the pipe protector being mounted to the pipe 8. The pipeline 8 may be a water pipe commonly used in life, a liquid cooling pipeline 8 used for conveying cooling liquid in a data center, or other pipelines 8 used for conveying liquid. In the liquid-cooled piping system, the piping guard is attached to the liquid-cooled piping 8. The liquid cooling pipeline 8 can comprise a main pipeline 8, a pipeline 8 connected with a liquid trap of the liquid separator, a pipeline 8 connected with a server, a reducing pipeline 8 and the like.

In some examples, the pipe 8 is provided with a plurality of preset positions, the number of pipe guards being a plurality, and the plurality of pipe guards being mounted to the plurality of preset positions of the pipe 8, respectively. The preset position is a position where the pipe 8 is likely to send a leak, for example, a position where two pipes 8 are connected, and may be other positions of the pipe 8. Therefore, a plurality of liquid cooling pipeline protection devices are arranged at a plurality of positions of the pipeline 8, when liquid leakage occurs at a certain preset position of the pipeline 8, the leakage sensor 7 of the corresponding pipeline protection device sends out alarm information, and maintenance personnel can accurately position the position where the leakage occurs and quickly go to maintenance.

Specifically, each of the pipe guards may be provided with a first leakage sensor 71, a second leakage sensor 72, and a third leakage sensor 73. When the leakage sensors 7 of the plurality of pipeline protection devices send out alarm information, maintenance personnel can distinguish leakage conditions of the pipeline protection devices at different preset positions according to the alarm information sent out by the leakage sensors 7. For example, when the first leakage sensor 71 of the pipe protector at a predetermined position gives an alarm, it indicates that the liquid leakage has just occurred at the predetermined position. When the third leakage sensor 73 of the pipe protection device at another preset position sends out alarm information, the preset position is prompted that the liquid leakage is serious, the safety of external equipment is threatened, and emergency repair is needed. Therefore, through the alarm information sent by the leakage sensors 7 with different pipeline protection devices, maintenance personnel can judge the severity of liquid leakage at a plurality of preset positions, so that more targeted emergency work can be carried out, and the pipeline 8 with the most serious liquid leakage can be selected for preemptive repair.

Referring to fig. 1-5, in some examples, the duct 8 includes a first duct 81, a second duct 82, and a connection structure 9 connected to the first duct 81 and the second duct 82, and the duct guard is mounted to the connection structure 9. Therefore, the pipeline protection device is arranged at the connecting position of the two pipelines 8, and the connecting position is also a position where liquid leakage is easier to occur, so that more accurate protection of the pipelines 8 is realized. Specifically, the connection structure 9 may be a threaded connection, or may be other connection structures 9 such as a pagoda connection, a press-buckle connection, or the like.

While the utility model has been described in detail in connection with the drawings and embodiments, it should be understood that the foregoing description is not intended to limit the utility model in any way. Modifications and variations of the utility model may be made as desired by those skilled in the art without departing from the true spirit and scope of the utility model, and such modifications and variations fall within the scope of the utility model.
